Will the real drummer please stand up! Will Ferrell and Chad Smith are finally coming face-to-face—with a drum-off battle! The actor and Red Hot Chili Peppers drummer have been taking playful jabs at each other over the past few months about getting mistaken for one another in public. To end the feud once and for all, they will go head-to-head on The Tonight Show With Jimmy Fallon on Thursday, May 22.

"We're going to have a drum-off to see who the real Chad Smith is," Smith, 52, toldRolling Stoneexclusively. "I'm all for it. But unless Will's been practicing or is secretly a crazy, wild drummer, I think it'll be evident right off the bat who the real Chad Smith is. I'm ready to take him down."

Back in January 2013, Smith sounded off on the 46-year-old actor trying to be him. "Ever since the Super Bowl, this delusional imposter claiming to be me has forced me to defend my identity," he said during an interview with Sydney's Big Day Out. "What's up with that? I don't understand why he, all of a sudden, decided he wants to be me. It's not enough to be one of the biggest movie stars in the world? It is going to be complete public humiliation on the part of Will Ferrell." (The men have also posted separate videos trying to get a rise out of the other.)

The stars will be raising money for Cancer for College and Little Kids Rock during their friendly competition, and the winner will get to take home a golden cowbell. (Ferrell famously took part in the skit "More Cowbell" with Christopher Walken on Saturday Night Live back in April 2000.) As for who will come out on top, well, Smith seems to be the frontrunner for now.
